I guess I am missing something here. Why wouldn't a small business have an IP office? I think there is much misinformation going on with this thread. You can install an IP office and not even use the IP part of it, install complete system with digital phones.
Paperless phones in itself is one GREAT reason to go the IP office route. Small businesses that have grown from 3-5 lines to 15 now has the option of installing a PRI or a full T1 (not half of one) without the huge cost of upgrading the entire system to a MAGIX. Partner systems are ok, but just arent flexible enough. The expandability isn't that great either. As far as pricing, almost the same after everything is said and done.
To be able to break up data circuits internally and no longer need routers, etc. Pretty much an all in one solution.
I think it is easier to program an IP office than a Magix by a long shot.
Instead of looking at it as marketing towards IT companies, look at it as marketing it towards Telco companies (that are able to grasp technology) being able to provide networking.
Guess I just see things in a positive rather than negative.
